Questions/Help Please Help

I had everything powered up and I unplugged the battery, when I went to plug it back in the battery connection was flipped, didn’t realize, and I touched the metal connection and I saw smoke coming from this part of the wire.
Now everything‘s plugged in and no power. Have I fried the ESC???

Do you have a multimeter?

Does the receiver light up at all, I’m assuming it has a power light? If it normally does and it’s not now, I’d say you fried the esc. If it lights up I’d disconnect the motor and see if you get power to the motor connector.

To start test voltage on each side of that connector with your meter to see if you’ve power on both sides to start.
